SHAPING-MACHINE Specification of Letters Patent.

Patented April 6, 1909.

Application filed June 1, 1908. Serial No. 435,891.

and State of Ohio, have invented a certain new and useful Improvement inShaping- Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, whichforms part of my specification.

My invention relates to shaping machines and particularly to theconstruction of the column and the manner of supporting the crank gearjournal thereon.

The object of my invention is to provide a simple construction of thecolumn wall and method of attachment of the housing by means of which astrong, rigid and long bearing for the crank gear journal may besecured.

My invention relates to the same general type of machine as that shownin the application of James C. Steen and Norman B. Ohace, Serial#307,002, filed March 20, 1906, shaping machines.

The drawing presents a vertical section through the column of a shapingmachine on the plane passing through the axis of the crank gear, thegear itself, however, being shown in elevation.

A is the column, B, the ram, C, the crank gear, I), the rocker arm, andE, the crank gear journal.

A is the supporting wall of the column and F the housing in which thecrank gear journal. is supported. The housing F approximates a cone inshape and is provided at its column end with a cylindrical extension fand with a circular flange f at right angles to said extension, adaptedto bear against the outer wall of the column. The wall itself is doublein construction compris- .ing the two plates a c, joined together at thehousing by a cylindrical flange a. The cylindrical projection f of thehousing fits snugly within the flange a which joins the two portions ofthe wall.

The crank gear journal comprises concentric cylinders G G, the one oflarge diameter and the other of considerably smaller diameter. Thecylindrical projection f is turned down on its inner face to form abearing for the cylinder G and the outer end of the housing forms abearing for the cylinder G.

It is unnecessary to describe the operation of the crank gear and theother parts of the machine as they do not in any way relate to myinvention.

It is apparent that by the construction described a rigid support forthe housing F is secured and this in a very efiicient and economicalmanner, and in addition the necessary support is produced withoutdeparting from the simple lines of the ordinary shaping machine.

Having thus described my invention,what

I desire to claim as new and to cover by Letters Patent is 1. In ashaping machine, in combination with the crank gear, the journal formedon said crank gear, comprising cylindrical bearing surfaces, one oflarge diameter adj acent the gear, and the other of reduced diameterprojecting beyond the first, and a housing having similar bearingsurfaces,

the column of the machine, the supporting wall thereof comprising twoplates at a distance from each other and joined together at the housingby a cylindrical flange, the larger bearing cylinder of the housinglocated within this flange and the housing having a flat disk restingagainst and secured to the outer plate of the wall.

2. In a shaping machine, in combination with the crank gear, the journalformed on said crank gear, comprising cylindrical bearing surfaces, oneof large diameter ad-.

j acent the gear, and the other of reduced diameter extended to adistance beyond the gear, and a housing having similar bearing surfaces,the column of the machine, the supporting wall thereof comprising twoplates properly braced and supported at a distance from each other andjoined together at the housing by a cylindrical flange, the housinghaving a cylindrical flange fitting within the flange joining the saidplates and a disk-like flange at right angles thereto resting againstand secured to the outer plate of the wall.
